I might be over looking this but I have looked and I don't see any list of what size tanks people use. I know it depends on the fish you are after so here are some I'm hoping to catch this spring.
Banded Pygmy Sunfish (or any others I might be able to catch in the area)
Darters (There are a lot in Indiana so it will depend what I can find)
These will be small fish so not sure if a 10g will work or if they need 20g tanks. I also know it depends on the number if fish in the tank but I'm not expecting to catch a lot of fish the first times out.
My goal is to have 4-5 tanks setup with plants ready to go so when I come home with fish I can put them right in. I will seed the filters tropical fish tanks for a few months then move them over when I add the native fish.
